Question about 1987 Volvo 240
The vents blow warm air on the main panel and floor, but not the defrost to heat the windshield, nothing blows out of the vents. When I close all the vents and push in the defrost button, nothing happens. The windshield keeps fogging up and gets ice on the inside of it. Can't see while driving, what should I do?
You have a problem with the vacuum operation of the dampers that control the direction of the airflow. You will need to pull the front panel of the console and look at the vacuum hoses that attach to the back of the control buttons. If those are attached, look under the dash to see if they are attached to the small bellows that control the dampers. You should pull the glove box out so you can see the damper under the dash to get a look at it and get an idea for how the other one looks. There is a second damper to the left of the one behind the glove box. Behind the bellows there is a small nipple that any loose hoses should be attached to. Take a flashlight along when you start exploring. If those are okay, check the other side.
